We're dividing 23586735 by 138 
Let's see how many times 138 fits into 23586735.

On to step 1:
If we divide 2 by 138, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 138

Moving on to step 2:
If we divide 23 by 138, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 138

Going ahead to step 3:
The number 138 fits into 235 1 times, leaving a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 138 from 235 and we're left with 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 138

Moving on to step 4:
138 goes into 978 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 17.0
If we take 966 away from 978, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 138

Moving on to step 5:
138 goes into 126 0 times with a remainder of 126.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we take 0 away from 126, we end up with 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 138

On to step 6:
138 goes into 1267 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 1709.0
Subtract 1242 from 1267 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 138

Going ahead to step 7:
If we divide 253 by 138, we get 1 and a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 17091.0
Subtracting 138 from 253 leaves us with 115.
Take the next digit (5) from the dividend and append it to 115, then repeat: 1155 / 138

Going ahead to step 8:
The number 138 fits into 1155 8 times, leaving a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 170918.0
The remainder is 51 after subtracting 1104 from 1155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
If we divide 510 by 138, we get 3 and a remainder of 96.
The number 3 becomes the next digit in our result. 
Result so far: 170918.3
Subtracting 414 from 510 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
The number 138 fits into 960 6 times, leaving a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 170918.36
If we subtract 828 from 960, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
138 goes into 1320 9 times with a remainder of 78.
The next digit of our result is 9. 
Result so far: 170918.369
If we take 1242 away from 1320, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
When dividing 780 by 138, we get 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 170918.3695
If we take 690 away from 780, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
900 divided by 138 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 170918.36956
Deduct 828 from 900 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
138 can be fit into 720 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 170918.369565
If we subtract 690 from 720, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 15:
When dividing 300 by 138, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 170918.3695652
Deduct 276 from 300 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
If we divide 240 by 138, we get 1 and a remainder of 102.
Put 1 as the next digit of the answer. 
Result so far: 170918.36956521
Deduct 138 from 240 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 170918.36956521 and a remainder of 1.02e-07.
